[Openev-discuss] area tool changed signal

[Gillian W. <gil...@at...>]

Hi,

Recently I discovered that the area tool does not emit a "changed" 
signal when the user finishes creating or changing a shape if the layer 
is initialized as a regular shapeslayer rather than a gvarealayer.  This 
is causing problems in some of our applications, as there is no way to 
detect when editing has finished without connecting separately to the 
button release event and using the fact that the area tool uses the 
right mouse button to finish editing.  The tool does emit a signal at 
the start of the changes (either "add" or "replace"), but there is 
nothing to indicate when editing is finished.  Does anyone know of a 
valid reason why this signal is not sent?  If there are no objections 
(ie. emails to this list saying "no no! <reason>" in the next day or 
so), I plan to add this.  I only intend to add a "replace" signal at the 
end of the changes, in gv_area_tool_stop_drawing, rather than every time 
a node is added (all the undo information is stored in a single memento, 
so I am treating the node additions as a single unit).
